Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Several studies have shown the efficacy of spinal cord stimulation in reducing the intensity of neuropathic pain. This efficacy is defined as obtaining relief of at least 50% of the preoperative pain intensity assessed by the visual analog scale or the digital pain scale. No study has evaluated the efficacy of stimulation specifically on the different components of neuropathic pain, only an overall improvement in pain has been described.

A specific questionnaire for neuropathic pain has been extensively validated in neuropathic pain: the Neuropathic Pain Symptom Inventory (NPSI).

Thanks to the multidimensional structure of this questionnaire, investigators propose to evaluate separately and in a much more specific way the efficacy of spinal cord stimulation in the short and long term on the different components of neuropathic pain and to define responders subgroups.
